' FLOATLESS cnmaunmnn.

Specification of Letters Patent.

Patented Jan. 28 19il5.

Application filed. February 24, 191% Serial No. 820,682.

To all whom it may concern:

Be it known that I, JOHN DREssnL,

citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and iiseful Floatless Carbureter, of which the following is a specification.

' My invention relates to improvements in carbureters and the object of my invention is to provide a floatless cprbureter of simple design and adjustment into which a volatile liquid is injected in a fine spray, such asis suitable to be readily vaporized. The carbureter as described in the annexed drawings and specifications will also give a greater efiiciency to the motor and will be a more economical device to operate, as it will give increased power while still using a smaller amount of gasolene.

WVith the foregoing and other objects in.

view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood.

that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed Without departing from the spirit of the invention.

In the drawings there is illustrated a vertical central sectional view through the complete carbureter.

Similar letters of reference refer to similar parts throughout the drawings.

In detail 10 is a mixing chamber of the carbureter; 11 is a butterfly valve for adjusting the flow of gas to the intake manifold; 12 is the air intake valve; 18 is a nozzle provided with an orifice; 14, through which the gasolene is sprayed.

The size of the orifice 14 is adjusted by the needle 15 by screwing it one way or the other as may be desired in the sleeve 16, a hollow tube 17 is secured to the mixing chamber 10, and at the lower end of this tube is secured a valve housing 18.- The lower end of the valve housing 18 is thread ed for a pipe connection from the gasolene feed pipe. There-is an opening 19, through which the gasolene, or similar liquid, flows when the valve 20 is unseated.

The .valve 20 is supported by a rod 21, the upper end of which has at head 22, which is held in a receptacle 23, into which is secured aplunger 24, made preferably of light material. The valve 21 is kept in alinement with its seat by a guide 25, which is also a stufling box and which is secured in the valve housing 18 at its upper end. The valve 20 has a flange 26, and between this flange and the lowerside of the valve guide 25 is a coil spring 27, which is adapted to return the valve 20 to its seat after having been opened. Near the lower end of the housing 18 is a gasolene outlet for supplying the nozzle 13 with gasolene, comprising of pipe connections 29 and tube 30 and the projection of the mixing chamber 31.

The operation is as follows: "When the motor is started, the suction of the piston, or pistons, of the engine creates a vacuum in the manifold and mixing chamber 10,

thus causing the plunger 2% to rise in the tube 17, and through the connections heretofore described, the plunger raises the valve 20 from its seat, allowing the gasolene to flow from the feed pipe to the inside of the valve housing 18, from which it flows through the outlet pipe to the nozzle 13 and is sprayed into the mixing chamber ,10, where it is vaporizediand mixed with the air flowing through the air intake 12 into the mixing chamber, and the gas thus formed flows through the intake manifold to the engine. The valve 20 will remain unseated as long as the engine continues running and allows the gasolene to flow continuously to the nozzle.

What I claim as my invention and desire to secure by Letters Patent is:

1. A carbureter, including a cylindrical casing open at one end and having an air inlet opening at one side intermediate of its ends, a fuel jet disposed in the casing at a point adj acent'to the air inlet opening, a pipe leading from the jet and to a point below the sealed end of the casing, a valve casing carried upon the sealed end of the casing and in communication with said pipe, said valve casing being coaxial with the axis of the casing, a conical valve mounted in said casing for vertical movement, a spring mounted therein for closing said valve, a stem connected to said valve and projecting into the casing through'the sealed end thereof, a vacuum actuated plunger mounted in the sealed end of the cas ng below the air inlet opening, and a loose coupling connecting the stem of the valve to said -plunger.

' ends, a fuel jet disposed in the casing 2. A carburetor, including a cylindrical casing open at one end and having an air inlet opening at one side intermediate of its at a point adjacent to the air inlet opemng, a

pipe leading from the jet and to a point below the sealed end of the casing, a valve casing carried upon the sealed .end of the ger mounted for reciprocation within the sealed end of the casmlg at apoint below the air inlet opening t reof, a stud carried concentrically of and depending from the under side of the plunger, a cap fitting thereupon and provided with a chamber, said cap being provided with an opening to receive the stem of the valve, and a head fixed upon the stem of the valve and mounted in the chamber of the'cap and forming therewith a loose connection between the plunger and valve.-
